There are three main connection methods when connecting galvanized pipes, namely wire type, welding type and rolling groove type. 1. If the thread type method is used, the thread buckle cannot be in complete contact with the pipe hoop of the steel pipe, otherwise it is likely to become loose. Before connecting, it is necessary to measure whether the…
Read MoreSubmerged arc welding is an important welding method. Its inherent advantages of stable welding quality, high welding productivity, no arc and little smoke make it an important steel structure in the production of pressure vessels, pipe sections, box beams and columns. the main welding method.In recent years, although many new welding methods with high efficiency and high quality have…

Read MoreWelded steel tube weld pores not only affect the tightness of the pipeline weld and cause pipeline leakage, but also become the induction point of corrosion, which seriously reduces the strength and toughness of the weld. The factors that cause porosity in the weld are: moisture, dirt, oxide scale and iron filings in the flux, welding components and covering…

Read MoreWeld leveling of straight seam steel pipe (lsaw/erw): Due to the impact of the welding current and the influence of gravity, the internal weld of the pipe will protrude, and the external weld will also sag. If these problems are used in an ordinary low-pressure fluid environment, they will not be affected. If it is used in high temperature,…
Read MoreThe welding process of high-frequency welded steel pipe (erw) is carried out under the condition of fast heating rate and high cooling rate. The rapid temperature change causes a certain welding stress, and the structure of the weld also changes. The structure in the welding center area along the weld is Low-carbon martensite and small area of free ferrite;…
Read MoreStraight seam welded pipe: a steel pipe with the weld seam parallel to the longitudinal direction of the steel pipe. According to the forming process, it is divided into high frequency straight seam steel pipe (erw pipe) and submerged arc welded straight seam steel pipe (lsaw pipe). 1. Construction preparation before use of straight seam welded pipe The pipeline…
